Over the years within your typical industrial production installation staff and processing machines have traditionally worked separately. Today, with the growth of smart factories and people and machines working in unison the equipment’s ability to recognise interaction with their human counterparts becomes ever more apparent.
Switches and actuators that can disable safety guards and doors are still being used at production facilities, which has proven to be one of the contributing factors in causing serious workplace accidents. However, there was another problem. Machines could not be operated immediately when using switches with small indicators because it took time to check the open/closed status of the doors of the entire production installation.
To try and solve this problem the engineers at Panasonic developed the SG-P Series Safety Door Switches. These durable safety switches enable operators and engineers to view the open/closed state of safety gates, guards of an entire production installation at-a-glance. These clever safety switches incorporate a switch unit and a paired actuator. During operating the switches only detect their matching actuator, this prevents the intentional disabling of the safety interlock and increases the safety of workers during operation and servicing. Other advantages include reducing machine downtime and improving productivity and through-put.

Prevention of the disabling of interlocks
During the maintenance of industrial production installations, intentionally disabling interlocks when opening equipment doors can be a major cause of accidents in the workplace, such as when another user operates the machine without noticing someone is still inside. The SG-P safety door switches prevent intentional disabling by utilising RFID that detects only the actuator that has been paired with the safety door switch.
Large and bright indicators show the open/closed state of the safety doors
These safety door switches are equipped with a bright and highly visible indicator, despite their small stature. Open safety doors and guards display a bright red light, other safety doors linked to the open doors are identified with green flashing lights to show that there is an unsafe status.
Traditional switches with a small indicator light are not easy to see when mounted on the inside of safety doors, making it hard for staff to identify which doors are open. Overcoming this problem, the Panasonic SG-P visible type features an actuator and switch that are both illuminated, while the switch body of the compact version illuminates on both sides, the actuator has no lighting. This highly visible status identification allows operators to ascertain the switch status and rapidly identify which doors are open, improving safety, reducing machine downtime and increasing through-put.

Parent-child structure saves wiring, up to 30 units to be connected in series
Up to 29 sub switches (child devices), can be connected to one safety switch which functions as the parent allowing up to 30 units to be connected in unison. Only the parent device provides an output which eliminates the need for wiring of the linked child devices, saving installation time, equipment
